ORE-CRUSHING MACHINE.

To all whom it may concern.-

Be it known that I, WILs N WARING, of Colora, in the county of Cecil and State of Maryland, have invented certain Improvements in Ore-Crushing Macl1ines,of which the following is a specification.

This invention relates to certain improvements in machines for crushing ores, phosphate-rock, and other hard substances, and specifically to a peculiar construction of the conical crusher-head,which is revolved within the shell,whereby the operative surface of the head, which is furnished with projections adapted .to engage with others on the shell, may be easily renewed in case it becomes Worn or broken, as hereinafter described.

In the description of the said invention which follows, referenceis made to the accompanying drawings, forming a part hereof, and in which A Figure I is a vertical section of the shell and part section of the crushing-head. Fig. II is a top View of the crushing-head, and Fig. III a bottom view of the same.

A is the shell,which requires no special description herein, as it forms no part of my present invention.

B is the crusher-head, which consists of a cylindrical block, a, having a tapering central hole to admit of the attachment of the block to the shaft 0. The operative surface of the crusher-head is formed of segments 12, having the usual crushing projections, 0. These segments are tapered so as to give conical form to the head, and have dovetailed tongues,

which fit in similarly-shaped grooves extending lengthwise of the block.

In the drawings the head has four segments only; but any convenient number may be employed. These segments are shown as in two parts each-that is to say, each segment is in two lengths. By this construction the surface of the head is composed of eight sections or parts, any one of which may be easily removed if broken and another substituted for it.

As the segments are applied to the central block by merely sliding their tongues in the grooves in said block, it will be seen that in the renewal of any of the segments it is not necessary to remove the head from the shell. The tongues are slightly tapered to insure a close fit within the grooves.

The principal advantage of the construction here shown is, that the segments are each selfsustaining, no other devices being necessary to hold them in place.

I claim as my invention In a crushing-head,a central cylindrical block having a series of tapered dovetailed grooves extending longitudinally thereof, combined with a covering having an outer conical surface formed of segments, each one of which has a tapering dovetailed tongue adapted to fit in a groove in the said block, and provided exteriorly with the usual crushing projections, substantially as specified.
